A number line with arrows on both the ends ranges from 0 to 15 in 1 unit increments. Closed points are marked at 8 and 15.

Jones uses the subtraction algorithm to subtract 8−15 and gets the answer −7. They want to connect this expression and answer to a number line model. How should they complete their number line model to show why the answer is −7?

(2 points)
Jones should draw an arrow starting at
that connects to
. The arrow will show that they need to move
in the negative direction to connect the two numbers. Therefore, the answer is −7.

Since Jones is subtracting 8 from 15, we should start at the point marked 15 on the number line. Then, draw an arrow to the left towards the point marked 8. This arrow will show that Jones needs to move 7 units in the negative direction to connect the two numbers. Therefore, the answer is -7.

Based on the given information, Jones should draw an arrow starting at 8 that connects to 15. The arrow should be pointing in the negative direction, indicating that they need to move 7 units in the negative direction to reach 15. Therefore, the answer is -7.
